ABSTRACT:
A plow system that includes a plurality of equally spaced plows, each of which is mounted on the inclined beam of the system by a mechanically adjustable mounting structure. The system also has a tail wheel that is associated with the last plow and steering linkage for the tail wheel. The mounting structure includes a generally vertical bore for rotational attachment to the beam and a laterally extending ear located adjacent the beam. A combination of a fastener and tapered shims between the ear and beam provide and maintain the desired furrow widths. The rotation of the plow system to correspond to the desired furrow width in conjunction with the steering linkage automatically positions the tail wheel for this furrow width.
